REPTILES OF MASSACHUSETTS. 243 



men is darker. The anterior extremities are olive green above, 

 with occasional spots of brown, and flesh colored beneath ; the 

 fingers are four in number, distinct, and each terminating in a 

 viscous pellet. The posterior extremities are long, green 

 above, obscurely blended with dark brown, and ficsh colored 

 beneath, tinged with ye'low externally ; the lower surface of 

 the thigh is granulated ; the toes are five in number, and semi- 

 palmatcd. 



Dimensions. Length of the body and head, 1 1-4 inches ; 

 of the thigh, 4-5ths of an inch ; of the leg, 4-5ths of an inch ; 

 of the tarsus and toes, 9-lOths of an inch. 



Geographical distribution. Its most northern limit must be 

 considered as lat. 34° ; we have no evidence of its being found 

 farther north. It abounds in South Carolina, Georgia and 

 Florida; how far west of these States it may exist cannot at 

 present be determined. 



Habits. This animal is found on trees, often seeking shel- 

 ter under the bark of such as are decaying ; it frequently 

 chooses old logs for its place of hybernation. In fine weather 

 and after showers, it climbs even the highest trees in search of 

 insects. 



General remarks. The colors of this animal are even more 

 changeable than in any species with which I am acquainted. 

 I have seen it pass in a few moments from a light green, un- 

 spotted and as intense as that of Hijla lateralis, to ash color, 

 and to a dull brown with darker spots ; the spots also at times 

 taking on ditlerent tints from the general surface. The mark- 

 ings, too, vary exceedingly in different individuals, the white 

 line on the upper lip and the band between the orbits alone 

 presenting some constancy. Daudin remarks that the leg is 

 " shorter than the thigh ;" we have found them nearly equal 

 in length, and this character is by no means so conspicuous as 

 in H. versicolor. 



Daudin first described this animal, and gave a figure of it, 

 from a drawing furnished him by Bosc. Lecontc has given 

 the latest and most detailed account of it, establishing three
